My father's birthday is on the 4th of July and when I was young, I used to think all the fireworks and celebrations were to celebrate his birthday. It made sense to me because my dad was so special. :-)
Learning that the whole city wasn't celebrating my dad's birthday was a bigger shock than learning that ...you know...Santa Claus thing.
